METHOD FOR PRODUCTION OF THICK FILM RESISTANCE HEATER Russian patent published in 2012 - IPC H05B3/00 

FIELD: electricity.

SUBSTANCE: method involves preparation of a substrate with subsequent application of an insulation, a resistive and a protective layers onto the substrate; the insulation layer is applied by the pneumatic-and-electrostatic method onto the current-conducting layer applied onto the substrate surface by the mesh screen print method; the resistive layer is formed of at least two layers; the first layer is applied by the mesh screen print method while the subsequent resistive layers are formed by the pneumatic-and-electrostatic application method and are coated with a protective dielectric layer.

EFFECT: manufacture process reduction more than twofold along with material consumption reduction and reliability enhancement.
